Title: Lateral stretching of thermoelastic films
IPC: B29C55/08
Filed: 1950-05-17
Abstract: <PICT:0689395/IV (a)/1> <PICT:0689395/IV (a)/2> <PICT:0689395/IV (a)/3> Lateral stretching of thermo-elastic films, e.g. of cellulose acetate and rubber hydrochloride, is effected by passing the film in heated condition alternately over and under a plurality of rolls rotating on bowed stationary shafts with the concave side of one roll in contact with the convex side of the next, and cooling the film, after it leaves the bowed rolls, while maintaining it in stretched condition, until it has set.  The film is preferably maintained in the stretched condition during cooling by passing it alternately over and under a plurality of contacting rectilinear cylindrical rolls. As shown (Fig. 3), thermoelastic film is withdrawn from roll 3 and is passed over guide roller 4 and heating drum 5 and then through a heated chamber containing a plurality of the stretching rolls.  Each stretching roll comprises a driven rubber sleeve 1A, 1B, 1C ... which is mounted for rotation on a stationary bowed shaft 33A, 33B, 33C ..., the sleeves of successive rolls being in contact and each sleeve being of a greater length than the one preceding it.  The film is passed under and over alternate rolls, is withdrawn from the last roll 1HH (Fig. 7) and then cooled and set as it is passed under and over alternate rotating rectilinear cylindrical rollers 6-14, being finally passed over floating roller 15, roller 16 and between rollers 17, 18 to wind-up roller 19.  Cooling may be effected by blowing with air or, alternatively, the rollers may be water-cooled.  The rubber sleeve of each stretching roll (Fig. 4) is supported by a plurality of discs 40 which are loosely mounted for rotation on the stationary bowed shaft, each disc being thicker at its centre than at its circumference.

Title: Terminal insertion apparatus
IPC: B23P21/00
Filed: 1975-03-25
Abstract: 1490274 Inserting terminals in substrates; force fits AMP Inc 25 March 1975 [28 March 1974] 12295/75 Headings B3A and B3U Apparatus for simultaneously inserting a plurality of electrical terminals into respective holes in a substrate, the terminals initially being carried by a common carrier strip (12), Fig. 1 (not shown), comprises a base 19 having support means 20, 21, for the terminals and carrier strip which also aligns the terminals relative to each other, and the carrier strip; terminal securing means mounted on the base for movement relative thereto between a first and a second position; and locking means which locks the securing means to the terminals in its first position and releases the securing means for movement to its second position after part insertion of the terminals. A comb 10 of terminal posts 11 is placed, either manually or automatically, on the support means with the carrier strip (12) located in a groove 24 formed between push and control blades 20, 21. Projections 22 on the blade 20 align the posts for insertion into a printed circuit board. A handle member 26 is moved forwardly, Fig. 4, to the first position and a portion 29 of the member carries a blade assembly 25 along with it by means of a detent pin 37. As the pin draws level with a channel 40 in a nose member 32, it is driven into the channel 40 thereby locking the handle member 26 to the nose member and releasing it from a bearing portion 28 of the blade assembly 25. A spring 36 then moves the portion 28 to place a control bar 27 over the terminal posts 11 to support and align them as they enter their respective holes in a printed circuit board. When the bar 27 contacts the board, the blade assembly 25 moves rearwardly against the spring 36 until the detent pin 37 drops out of the channel 40, thereby unlocking the handle assembly 26 from the nose portion 32. A spring 35 moves the handle assembly rearwardly to the second position. Insertion of the posts continues until shoulders 14 on them engage the circuit board whereupon the apparatus is removed from the comb 10 and the strip (12) broken off. The comb is stamped, cut or machined from a single piece of conductive material, e.g. copper, gold, plated steel or the like.

Title: Travelling-wave electron discharge tube
IPC: H01J25/44
Filed: 1950-05-18
Abstract: 677,586. Travelling-wave tubes. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. May 18, 1950 [June 2, 1949], No. 12471/50. Class 39 (i). In a travelling-wave amplifier in which the electron beam moves in a direction normal to crossed electrostatic and magnetic fields and parallel to a retardation line in which an electromagnetic wave is propagated at a phase velocity equal to that of the electron beam, the retardation line consists of a positive helix 1, Fig. 2, and a negative conductor 2 within the helix. The electron beam 3 travels inside the helix where the greater part of the power of the wave is propagated. In one embodiment, Fig. 4a, in addition to the electron beam propagated between the helix 1 and the internal conductor 2, a second electron beam is propagated between the helix and an external negative conductor 2<SP>1</SP> for interaction with the wave outside the helix. Opposite the two cathodes 6, 6<SP>1</SP>, are located auxiliary collectors 15, 151 for collecting the electrons in the absence of the magnetic field. The helix 1 is secured to longitudinal quartz or ceramic rods by a number of clasps. In another embodiment, Figs. 5a, 5b (not shown), the electrodes are bent round in a circle.

Title: Improvements in and relating to high speed electric controlling devices
IPC: H02H3/10
Filed: 1935-04-26
Abstract: 455,860. Protective cut-out systems. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. April 26, 1935, No. 12564. Convention date, April 27, 1934. [Class 38 (v)] A rotary converter 12 is connected to supply lines 10, 11 by means of a high-speed breaker 18 of the kind disclosed in Specifications 125,279 and 187,993, [both in Class 38 (v)], the flux-shifting winding 26 of which is energized on closure of either of the contacts 40, 78 of identical relays 38, 39, responsive to reverse current and normal overload, respectively. The movable contact 40 is biassed " open " by a spring 42 and carries an armature 41 co-operating with poles 50, 51 extending from a closed magnetic circuit 45, which is normally energized to saturation-point by the coil 46 with only a little leakage flux effective on the armature. With a reverse current flow the rapidly-rising current causes the m.m.f. of coil 54 to oppose that of 46, whereby the flux is shifted from leg 55 to the poles to attract the armature and close the trip circuit. The contact-separation in the open position is between one-sixth and one-thirty-second of an inch, and the time of operation between one-and-a-half and two-thousandths of a second, and with a breaker time of operation of six thousandths, the total time taken to clear the fault is eight thousandths of a second, which is short enough to protect the converter from flashover. Opening of the breaker may de-energize the coil 46 so as to assist the relay 38 to reset. The shunt 19 across which 54 is connected has an inductance valve relatively high compared to its resistance, and the shunt 14 supplying the trip coil 72 of relay 39 has an inductance value which is less in proportion to the resistance than is 19, so that the rapidly-rising current due to a reversal will affect 38 much more quickly than a slowlyrising overload, and shunt 14 is less sensitive to a rapidly-rising overload but more sensitive to slowly-rising overloads than shunt 19. The relays are therefore selective. To further speed up operation, the time-constant of coil 26 is kept low by means of a high resistance in the coil or as shown at 84, and a highvoltage source is provided, the circuit being broken at contacts 30 when 18 opens.

Title: Improvements in non-linear feedback circuit
IPC: G05B5/01
Filed: 1959-04-14
Abstract: 868,517. Semi-conductor limiter circuits. GENERAL ELECTRIC CO. April 14, 1959 [April 16, 1958], No. 12605/59. Drawings to Specification. Class 40(6) [Also in Group XXXV] In a control system, a pair of semi-conductor diodes having critical reverse voltage characteristics are reversely connected in series and associated with a feedback path so as to produce a non-linear or limiting effect for signals exceeding a critical value. In a system for automatically regulating the voltage of a polyphase alternator (see Group XXXV) undesirable effects of feedback from the alternator field to the regulator under fault conditions are prevented by a pair of serially reversely connected Zener diodes in a parallel circuit with the field winding to limit the magnitude or rate of change of the feedback signal to predetermined values, which may be different, in each sense. In a modification in which a feedback voltage is compared with a reference voltage, the diodes are connected in parallel with a series dropping resistor so that the feedback signal is increased under fault conditions.

[Class 17 (i)] For holding the shank portions of a pre-welted upper into conformed relation to a last, a resilient U-shaped loop has end portions adapted to be separated and placed in the welt crease with the plane of the loop at right angles to the longitudinal axis of the shoe. In a modification, for use when the edge of the upper is secured in a slit made at the edge of the welt, a second slit providing a flap to be cemented over the margin of the insole, the ends of the loop 24 are formed with inturned portions 28 to engage the end of a flap and a pair of fingers 26 at the sides of the inturned portions, to engage in the crease. The upper may be secured to the insole at the shank by a machine driving curved staples which do not penetrate the inner face of the insole, the machine having a guide roll 32 engaging the welt crease.

Filed: 1939-04-27
Abstract: 526,294. Labelling-machines. HOLM, C. April 27, 1939, No. 12678. [Class 73] In a labelling machine the bottles &c. are carried in a circular path past labelling and wiping stations by devices which oscillate about a vertical axis and are provided with grippers which engage the top and bottom of the bottle to move it step by step. A battery of labelling machines may be fed by conveyers branching from a main conveyer and discharge on to a common delivery table. The label applying devices are of known construction. The bottles are fed from a branch conveyer 11, Fig. 2, by a reciprocating pusher 12 having a surface 54 that supports the bottle which is engaged by a reciprocating member 50 fitted with a pad 53; the bottle then rests on a table comprising concentric members 19, 19a between which is a lower, circular, vertically reciprocating gripping member 13 carried by a sleeve 88. The upper ends of the bottle are gripped by spring- mounted caps 95 carried on radial arms 94 mounted on a central rod 74. The sleeve 88 is oscillated by an arm 106 thereon operated by a reciprocating rod 100, and imparts this motion to the rod 74 by means of a member 72 carried by the sleeve and sliding in a member 73 mounted on the rod. The rod is lowered and the sleeve raised during the forward movement of the oscillation to grip the bottles by means of a reciprocating slotted cam 35 operating members connected to forks 82, 84. The bottles are supported during the labelling and wiping operations by discs 9, the wiper comprising a resiliently mounted pad 41 carried by an upright 113 on a slide 39, an additional wiper 42 being provided for the neck labels. The bottles are then carried to the discharge station where they are ejected by a reciprocating member 123, Fig. 20, and are engaged by further wipers 143, 145 carried by arms 140 drawn together by a spring 139. The bottles are steadied on the discharge conveyer 16 by similar members 134, 136 mounted on spring influenced arms 130 which are given a reciprocating movement by means of a slide 126 engaging cranks 128. As shown in Fig. 28 a battery of machines are fed by conveyers 11 branching from the main conveyer 10, the discharge conveyers 16 discharging on to a common table 17.

Title: Improvements in spring suspensions for automobiles and the like
IPC: B60G15/02
Filed: 1923-05-14
Abstract: 220,084. Carwardine, G. May 14, 1928. Buffers; vibration-dampers; dash-pots. - An auxiliary spring suspension device for motor vehicles comprises a lever pivoted on the unsprung or sprung portion of the vehicle as the case may be, and a spring-pressed member cooperating with the lever and having such a shape that the resistance to the angular deflection of the lever decreases for the whole or portion of its range upon increase of movement of the lever. The combined suspension has a longer period of oscillation through the range in question than the primary suspension acting alone. The spring- pressed member may be further shaped so that it assists the deflection of the lever from a predetermined point in its range. As shown, a lever 5 connected to an unsprung portion of the vehicle is keyed on a shaft 4 which is mounted in a casing 2 secured to the chassis 1 and is rigid.with a lever arm 7 carrying a roller 8 engaging a lever 6 rigidly attached to a shaft 4, the rotation of which is resisted by a torsion or other spring. The lever 6 is shaped so that resistance to angular deflection of the lever 5 is in accordance with the law specified above. Rotation of the lever 5 may be damped by attaching thereto a friction ring 13, Fig. 6, engaged by an adjustable band 12 carried by the casing 2. The band is mounted on a slotted member 16 engaging a stop 14 on the casing so that the lever may have a limited movement without frictional restraint. In the arrangement shown in Fig. 8, hydraulic restraint is used instead of frictional. The levers 6, 7 are formed so that they provide a movable oil-proof partition dividing the casing into upper and lower chambers. Fluid passes from the upper to the lower chamber through the port 17<a>, hollow pulsating piston valve 17, and port 17b the travel of the valve being limited and adjusted by a screwed spindle 18 having a longitudinal flat 20 to permit flow of the fluid from the lower to the upper chamber through the passages 21a, 21. The flow in both directions is thus adjusted by means of the spindle 18, the resistance to rebound being preferably the greater. By increasing the diameter of the piston valve or making its movement large in comparison with the size of the ports, the lever 5 may have a limited movement without restraint.

Title: Improvements in or relating to automobiles and other vehicles in which the road-wheels are independently spring-suspended
IPC: B60G11/23
Filed: 1933-05-03
Abstract: 419,291. Motor-vehicle frames and driving - gearing. MACBETH, C., 67, Norwich Union Chambers, Birmingham. May 3, 1933, No. 12868. [Classes 79 (ii) and 79 (iv).] In an independent wheel-suspension for motor vehicles, in which the wheel a is mounted on a lever-arm b which extends parallel to the chassis frame and is controlled by a torsionspring unit, the wheel is driven by a cardan cross-shaft g extending through an arcuate aperture h in the side member f of the frame, rubber stops adapted to engage extensions of the arm being provided to limit the movements thereof. As shown in Fig. 1 a torsionspring unit of the kind described in Specification 363,039, [Group XXXII], supports a trailing road-wheel a, the fixed metal element e<1> of the unit being secured to a rigid cross-member c and the other element e<2> being splined to the lever-arm spindle b<1> which is journalled in inner bearings b3 housed in an extension e<3> of element e<1> and in outer bearings b<4> contained in a housing f<1> bolted to the chassis side-member f. The spindle, or the spindle, inner bearings, and spring unit, may be removed through the aperture f<2> in the member f covered by the housing f<1>, bodily with the wheel, lever-arm, and outer bearings. The brake shoe anchor plate is mounted on the wheel axle extension of the lever-arm so that when the brakes are applied the car body moves towards the ground. In a modified construction a universal bearing for an inward extension of the spindle b<1> is fixed to the cross-member c, the element el of the spring unit is fixed to the chassis sidemember which is cranked inwardly and given an inwardly-cambered vertical section in the region of the aperture h to allow sufficient clearance for the cardan shaft, and the spindle is made hollow to permit the passage therethrough of brake-operating connections. In another construction, Fig. 6, in which the leverarms are of the leading type, a tubular crossmember c carries end housings c<6> riveted to the chassis side-members and each containing a spring unit, the element e<1> of which is bolted to the inner end of the housing, the other element e<2> being fixed to the spindle b<1>. The brake-drums are mounted on shafts extending through the differential casing and are connected by universal joints to the cardan crossshafts, while the brake anchor-plates and brakeshoe operating-mechanism are mounted on the casing. When however the brakes are mounted on the wheels the brake-anchorage pin is attached to a floating bearing on the wheel axis, the bearing being connected to the chassis side member by a rod or parallel-motion links which take the brake reaction. In a further construction the rubber spring units are replaced by coiled springs. Specification 236,243, [Class 108 (ii)], also is referred to.
